Should you wish to use an image as a background to your Header (just like the one you see above or this colorful one), get an appropriate image and crop it to size, about 660×150 pixels. A photo editing software like Google’s Photo Editing Software Picasa or Photoshop would do the trick.
After that, upload the image to a free server. You can read about using free hosts like Google Page Creator and Google Groups. We also have a rather comprehensive list of free Image Hosts and File Hosting Services in our article on Manage Blogger Image Storage Space. Check out those sites and choose one that is fast, reliable and enables hotlinking to the uploaded files. Take note of the picture URL.
Next, go back to “Edit HTML” under Template tab. Scroll to where these lines appear:
#header-wrapper {
width:660px;
margin:0 auto 10px;
border:1px solid $bordercolor;
